Definitions
- the present invention relates to a coffee grinder assembly comprising a housing, a first, lower grinding wheel support member and a first, lower grinding wheel, and a second, upper grinding wheel support member and a second, upper grinding wheel. At least one of the first and second grinding wheels is rotatably received in the housing.
- the first, lower grinding wheel support member and the first, lower grinding wheel both comprise first cooperating connecting means for fixing the first, lower grinding wheel in the first, lower grinding wheel support member
- the second, upper grinding wheel support member and the second, upper grinding wheel both comprise second cooperating connecting means for fixing the second, upper grinding wheel in the second, upper grinding wheel support member
- Grinder assemblies of the kind referred to herein above consist mainly of plastic material, whereby the grinding wheels thereof are manufactured of a hard, non-abrasive material, for example of hardened steel.
- the quality of the coffee powder prepared with such grinder assemblies particularly depends on the wear resistance of the grinding wheels used in the grinder assembly, since, with progressive wear of the grinding wheels, the particle size of the coffee powder varies, resulting in decreasing quality both of the ground coffee powder and the coffee beverage prepared therewith.
- the wheels are provided with a plurality of bores, running through the grinding wheels and adapted to receive connecting means like screws, rivets or similar means.
- connecting bores may be seen in the fact that they claim a substantial amount of the theoretically available grinding surface of the grinding wheel, because the toothing of the grinding wheel is interrupted by these bores.
- connection bores has the further disadvantage that coffee powder is collected both in the bores an in the connecting means; of course, this is not desired at all due to hygienic reasons.
- the patent document EP 1,065,962 discloses a coffee grinder having a grinder assembly of the kind referred to herein above.
- the grinder assembly comprises a conical gear wheel as well as two coaxially arranged grinding wheels having a spiral-like toothing.
- One of the grinding wheels is stationary and the other one rotatable.
- Both grinding wheels are provided with connecting bores adapted to receive connecting screws by means of which the grinding wheels are fixed to the associated grinding wheel support members.
- FIG. 4 of this document clearly shows that the connecting bores are located in the region of the toothing of the grinding wheels.
- U.S. Pat. No. 6,164,574 discloses a mill for grinding material such as salt grains or pepper corns whose coarseness can be adjusted and whose grinding gear can be disassembled for cleaning.
- the mill has a middle part which serves as a reservoir for the material to be ground and an upper part which is attachable to the middle part by means of an attachment and adjustment element.
- the mill has a lower part which is designed to unscrew from the middle part for the purpose of cleaning the grinding gear.
- the grinding gear includes both an upper grinding wheel which is disposed underneath on the middle part and a lower grinding wheel which is screwed together with the attachment and adjustment element through a pivot pin.
- the pivot pin is connected in a non-rotatable way to the upper part. Turning the upper part actuates the grinding gear.
- the grinding wheels are provided with four recesses located along their periphery, which are engaged by correspondingly arranged cam members provided in the associated support member.
- Such a design shows the disadvantage that the grinding wheels cannot be positioned exactly neither in axial direction nor in radial direction, with the result that they can move within their support member under the influence of the torque forces occurring during the grinding operation.
- the present invention provides a coffee grinder assembly comprising a housing, a first, lower grinding wheel support member and a first, lower grinding wheel, and a second, upper grinding wheel support member and a second, upper grinding wheel. At least one of the first and second grinding wheels is rotatably received in the housing.
- the first, lower grinding wheel support member and the first, lower grinding wheel both comprise first cooperating connecting means for fixing the first, lower grinding wheel in the first, lower grinding wheel support member
- the second, upper grinding wheel support member and the second, upper grinding wheel both comprise second cooperating connecting means for fixing the second, upper grinding wheel in the second, upper grinding wheel support member
- Each of the first and second cooperating connecting means is designed as a rotational closure in which a mutual rotation of the first, lower grinding wheel support and the first, lower grinding wheel as well as of the second, upper grinding wheel support and the second, upper grinding wheel in each case provides for an interlocking closure that is driven in its locked position under the influence of the torque force occurring during the grinding operation.
- the grinding wheels comprise radially extending protrusions, cooperating with corresponding recesses provided in the associated support members in the kind of a bayonet closure. Such grinding wheels can be fixed in the associated supports quickly and easily.

- the bottom side of the rotating disc 2 can be provided with permanent magnets (not shown), cooperating with a sensor (not shown) fixed to the housing to measure the number of the revolutions when the coffee grinder is operated.
- a sensor not shown
- the number of the revolutions performed by the lower grinding wheel 5 during a coffee grinding cycle establishes a measure for determining the amount of coffee ground during one operating cycle.
- FIG. 2 shows a top view of the upper grinding wheel support 8 with the upper grinding wheel 7 fixed thereto
- FIG. 3 shows a cross sectional view of the grinding wheel support 8 and the grinding wheel 7 taken along line A-A in FIG. 2
- FIG. 2 clearly shows the slot-shaped recesses 13 provided in the upper grinding wheel support 8 which are engaged by the radially extending projections 10 provided on the grinding wheel 7 (cf. FIG. 1 ) for fixedly connecting the upper grinding wheel 7 to the support 8
- FIG. 3 particularly the annular protrusion 20 provided on the upper grinding wheel support 8 and the corresponding annular recess 21 provided on the upper grinding wheel 7 for centering the upper grinding wheel 7 with respect to the upper grinding wheel support 8 are clearly shown.
- the protrusion 20 of the support 8 engages the recess 21 of the grinding wheel 7 and radially aligns the latter one with regard to the support 8 .
- Corresponding protrusions and recesses are provided on the lower grinding wheel support 4 and the lower grinding wheel 5 as well, with the result that the two grinding wheels 5 , 7 are coaxial once the grinder assembly has been finally assembled.
- FIG. 4 shows an enlarged portion of FIG. 3 .
- the grinding wheel 7 is provided with a smooth back surface 14 , serving, amongst else, as a support face.
- the grinding wheel support 8 comprises an annular support surface 24 facing the grinding wheel 7 , supporting the grinding wheel 7 in axial direction, i.e. in the direction of the central longitudinal axis of the coffee grinder assembly.
- the annular support surface 24 serves for positioning the grinding wheel 7 in axial direction.
- the wheel 7 Due to the torque force acting on the grinding wheel 7 during the grinding operation, the wheel 7 is loaded in locking direction; in other words, by choosing a proper sense of rotation of the grinding wheel and due to the design of the rotational locking mechanism, the grinding wheel 7 is loaded in locking direction. Thereby, the grinding wheel 7 is firmly fixed in the grinding wheel support 8 and it is ensured that the grinding wheel 7 does not become loose unintentionally. Moreover, due to this load, it is also ensured that the rear side of the grinding wheel 7 is moved against the supporting surface 24 of the grinding wheel support 8 and rests there against without play. The result is that no coffee dust can accumulate between the grinding wheel 7 and the grinding wheel support 8 . It is understood that all of the above is also true in connection with grinding wheel 5 and its associated support 4 .
- FIG. 4 moreover, the annular protrusion 20 of the grinding wheel support 8 is clearly visible, engaging the annular recess 21 provided in the grinding wheel 7 and ensuring that the grinding wheel 7 is exactly radially positioned with regard to the support 8 .
- a threaded locking mechanism could be used for fixing the grinding wheel to the associated support member.
- the locking means could be arranged in axial direction on the grinding wheel, particularly on its rear surface facing the associated support member. Also, a central location of a protrusion or several protrusions would be possible.
- the locking mechanism could be designed in a kinematically opposite manner: The grinding wheels could be provided with a recess or with several recesses, and the associated support member could comprise one or several corresponding protrusions engaging these recesses in the grinding wheel.
